++ Setting up the METAR weather block
The documentation on the METAR weather block as well as the PEAR Services_Weather module is not too extensive and user-friendly.
Here is how it works:
+++ Prerequisites: install Services_Weather
You install the PEAR Services_Weather module as root from the command line:
<code>
pear install Services_Weather
</code>
then you change to your pear directory (usually {{/usr/share/php}}) and look for the {{data/Services_Weather}} directory
It contains a file {{buildMetarDB.php}}.
I assume you have the command line PHP interpreter installed and it's called "php" (some distributions call it "php5").
<code>
php buildMetarDB.php -a -u horde_db_user -p horde_db_pass -d horde_db
php buildMetarDB.php -l -u horde_db_user -p horde_db_pass -d horde_db
</code>
If database is not on localhost, you might add options {{-h <hostname>}} and {{-r tcp}}.
Note: I haven't yet found a way to use the METAR block if you use another database than the horde database.
The horde_db_user is often called "horde" and the horde_db is also often called "horde". If I knew all your passwords, I wouldn't tell you ;)
Now login to horde, go to the portal, choose METAR block and click the edit button in the upper right of the block.
The rest is self-explanatory click-and-play.

+++Error message: Services_Weather: Sourcefile nsd_cccc not found!
While executing the above commands:
<code>
php buildMetarDB.php -a -u horde_db_user -p horde_db_pass -d horde_db
php buildMetarDB.php -l -u horde_db_user -p horde_db_pass -d horde_db
</code>
You may receive the error message:
<code>
Services_Weather: Sourcefile nsd_cccc not found!
</code>
The reason is that the file downloaded by {{buildMetarDB.php}} script is empty (0 byte file size) as of August,2 2010.
Fortunately, there are alternate working links to this file on this page as TXT or ZIP format instead of the 0 file size GZIP one: http://weather.noaa.gov/tg/site.shtml
So, you should modify line 273 in {{buildMetarDB.php}} file from:
<code>
if (extension_loaded("zlib")) {
</code>
to:
<code>
if (extension_loaded("zlibXXXX")) {
</code>
This way the file will be downloaded as TXT format which is not empty, and you metar tables will be filled with appropriate data.
